The problem that the rosbag tool plotjuggler cannot open rosbag

Cause of the problem: This problem is because only plotjuggler is installed, but its plugin for rosbag support is not installed, so it can only be openedSome basic format files such as csv.

Resolution reference:

• ros(19): rosbag package drawing tool PlotJuggler: this is still installed from the command line, more convenient, and the test can also successfully solve the problem.

• PlotJuggler drawing tool cannot open rosbag file solution: Installed from source, not tested, should also be possible, but a little more troublesome.
